Correct Answer

B. (108)

Step 1

Concept

Here (a=13) and (d=5), so (a_{20}=13+19(5)=108). Use (a_n=a+(n-1)d) even for larger terms.

Step 2

Why this answer is correct

The correct answer is B. (108). Here (a=13) and (d=5), so (a_{20}=13+19(5)=108). Use (a_n=a+(n-1)d) even for larger terms.

Step 3

Exam Tip

यहाँ (a=13) और (d=5), इसलिए (a_{20}=13+19(5)=108)। बड़े पद के लिए भी (a_n=a+(n-1)d) लगाएं।
